Overview
MRI
On MRI, multiple sclerosis is characterized by cerebral and/or spinal cord plaques which are demyelinating areas.[1] These lesions are commonly ovoid, and located in periventricular white matter, cerebellum and brain stem.[2] These lesions are hyperintense on T2 sections of MRI. There are also gray matter lesions, presents as hypointensity in T2-weighted and are correlated with patients physical disability and brain atrophy.[3][4]
